python实现给字典添加条目的方法
具体实现方法如下:
def addWord(theIndex,word,pagenumber): theIndex.setdefault(word, [ ]).append(pagenumber)#存在就在基础上加入列表,不存在就新建个字典key d = {"hello":[3]} #d = {} addWord(d,"hello",3) addWord(d,"hello",56) addWord(d,"nihao",24) print d
本文测试环境为Python2.7.6
程序运行结果如下:
{'nihao': [24], 'hello': [3, 3, 56]}
